Abstract我国水能资源十分丰富,但目前仅开发了可供开发利用的5%左右。在发展水电时,淹没损失的估算是一个很重要的问题。而采用常规的野外作业方式进行淹没损失的调查,不仅野外工作量大,要花很大的人力物力,而且周期长,已不能满足水电发展的需要。为此,在二滩电站的淹没损失估算中,中国科学院遥感应用研究所曾采用过遥感分析的方法,并取得了开发性的成果。本文试图用航天遥感方法,对水库淹没损失进行估算,旨在为这类工作探讨一种新的方法。
Other Abstract The article primarily experiments a new method for estimating reservoir submergence loss from landsat. First, satellite image of experimental region, transformed to Gaussian coordinate, is registered to digital terrain image of the same region. Secondly, boundaries of reservoir submergence are determined with elevation and slope of digital terrain model (DTM). It develops a statistical method for modifying the error caused by calculating an area with grids. Land use of this region is classified by fuzzy pattern recognition, hybrid pattern (fuzzy cluster and fuzzy pattern recognition together), cluster and maximum-likelihood pattern. The classification accuracy of hybrid pattern is about 79.2 percent.The experiment shows that above method is able to satisfy the request of submergence loss survey for reservoir planning.The article paies special attention to the importance of incorporation of geography information with satellite data. Specially, the region, generally, speaking, is mountainous and study contents include many social and environmental problems which can’t reflected by remote sensing image. Therefore, this incorporation may greatly improve the level of estimating reservoir submergence loss by space renote sensing.
